Patch NSIS so that it's installer stubs, produced at NSIS build time,
do not contain .reloc sections, which will exist by default when using
binutils/ld 2.36+.
This ultimately fixes an issue when running the installer with the
"Force randomization for images (Mandatory ASLR)" setting active.
This patch has not yet been sent upstream, because it's not clear if this
is the best fix, for the underlying issue, which seems to be that makensis
doesn't account for .reloc sections when it builds installers.
The existence of a reloc section shouldn't be a problem, and, if anything,
is actually a requirement for working ASLR. All other Windows binaries we
produce contain them, and function correctly when under the same
"Force randomization for images (Mandatory ASLR)" setting.
